QUECHEE, VERMONT -- October 23, 2011 -- PFiddlesoft today announced that it has updated the PFiddlesoft Frameworks, two Cocoa frameworks for writing assistive applications for persons with disabilities using Apple's Accessibility and Quartz Event Taps APIs on Mac OS X 10.6 Snow Leopard and 10.7 Lion.

The PFiddlesoft Frameworks were updated today to include the PFAssistive Framework version 3.1.3 and the PFEventTaps Framework 1.3.3. This update adds support for new accessibility features introduced by Apple in Mac OS X 10.7 Lion, and it fixes a few minor bugs in the frameworks.

The PFAssistive Framework was created in 2003 as the engine driving PFiddlesoft’s highly regarded UI Browser application for developers and for users of Apple’s AppleScript GUI Scripting technology. The framework supports and enhances Apple's Accessibility API. The PFEventTaps Framework was created in 2007 as the engine underlying PFiddlesoft’s free Event Taps Testbench utility for developers. The framework supports and enhances Apple's Quartz Event Taps API. Both frameworks have been revised and updated over a period of years, and they have demonstrated their power and reliability in PFiddlesoft’s commercial and free developer utilities.

The frameworks are written using Objective-C 2.0. They are Universal Binaries supporting 32-bit and 64-bit architectures using reference counted memory management. Developers can now license the PFiddlesoft Frameworks for distribution or use with their own products that use Apple's Accessibility and Quartz Event Taps technologies. The frameworks may be licensed free of charge for personal use or for distribution or use with a free software product. A modest license fee is required to distribute or use the frameworks with a product for which payment is requested or required. Source code is available for a separate fee. Different terms apply to large or established commercial software developers. For more information, go to pfiddlesoft.com/frameworks/.
